How can I get a Page 2,3,4,etc. for unvalidated links in the admin pages when trying to validate links.

I need to skip a few and validate newer links.

Since you have received no replies, I would go in a different direction. I recall seeing a mod at some point (or perhaps one in the works) that allowed you to queue and remove submitted links from your main validation form.

I think that is exactly what you are looking for. Then at a later date you can go through the queued database a validate those.
